Subject: [PATCH 2/2] xfs: cancel failed transaction in xfs_fs_commit_blocks()
Date: Mon, 23 Feb 2015 13:00:27 -0600 [thread overview]
Message-ID: <54EB78CB.6050709@sandeen.net> (raw)
In-Reply-To: <54EB782F.8020201@redhat.com>
If xfs_trans_reserve fails we don't cancel the transaction,
and we'll leak the allocated transaction pointer.
Spotted by Coverity.
